I have a Tunze Nano DOC Protein Skimmer 9002for sale, i received it brand new several days ago but decided on going with a HOB style skimmer. I was originally going to use the skimmer in a 2nd tank if I decided on the HOB but the setup for the new tank is taking very long and I do not really have the luxury of additional space in my apartment for storage...
The skimmer was setup in my 20 gal to test and everything works fine on the unit. I have not made any mods and the unit hasn't been run for more than several hours and is in perfect condition.
I have all original packaging and instructions. I can ship ground to you for $125.
Also willing to trade for zoa's/chalices and we can work out any price differences. I generally use paypal for all transactions. Pics available upon request.
Thanks for looking!
